Thames & Kosmos Air-Power Turbo Racer STEM Experiment Kit

Build a lightning-fast race car powered by nothing but air — no batteries or electric motor required! Use the sleek, integrated pump to compress air into the tank, then put the car on the ground and watch it zoom away! The innovative air-powered engine works just like a combustion engine in gasoline cars, minus the burning of fossil fuels. The engine intakes pressurized air from the tank, which pushes the piston forward. The piston knocks against the valve, releasing air into the cylinder, which pushes the piston down, rotating the rear axle of the car. The piston expels the air from the cylinder, creating a puff of exhaust and a real engine sound. Vrooom! Vrooom!

• HANDS-ON BUILDING PROJECT FOR AGES 8+: Assemble a lightning-fast race car that's powered by nothing by air -- no batteries or electric motor required!
• SUPRISINGLY SPEEDY & REALISTIC! With just 12 pumps, the tank fills with air allowing the car to travel up to 13 feet per second (9 mph), reach distances of over 60 feet, and make engine noises as it zooms away!
• BUILT FOR LONG-LASTING PLAY: Durable building pieces are easy to assemble and designed to withstand multiple experiments, test drives, and races, guaranteeing hours of play and exploration.
• REAL-WORLD CONNECTIONS: Through assembly and experimentation, kids will learn about sustainable engineering design, clean technology, and essential physics concepts
• THOROUGH, EASY-TO-UNDERSTAND MANUAL: The 24-page, full-color manual guides assembly with step-by-step illustrated instructions and provides clear explanations of scientific concepts.
